To automatically generate a project document, a server in a computing environment receives input documents associated with a project, and extracts a set of features from each input document. The server determines a frequency of the words in each input document and stores the frequencies in relation to the words in the sets of words. The server than applies a document type machine-learned model to a set of words for each input document to infer a document type. The document machine-learned model may be trained using a bag-of-words representation. The server then applies a architecture pattern machine-learned model the set of input documents to determine a target architecture pattern. The server automatically generates a project document for the project based on the document types and inferred architecture pattern.
